Thanks LizzieCurry, I'll check it out to find out more information. The book is really interesting, although light on quotes from Tommy...
A few other ones I can think of that may or may not be in the book (I can't remember and don't have the book on me right now):
Marianne (as mentioned in the song) was Frankie's second wife and she's not mentioned in the show, but at that point it's kind of late to introduce a new character.
There's at least one song that Bob, Frankie, Nick, and Tommy perform in the show that I believe was actually written after Nick and/or Tommy had left the group. I can't remember which song, though.
Bob Gaudio was from the Bronx, and although they don't mention this in the show, they never really say he's not from Jersey, either.
